I don't know. I just don't know. In someways this was my kind of book, in some ways it wasn't. I'd probably give this more of a 3.5 rating.
It's a thick Victorian set mystery. The book is read as a confession, of course told in the first person. So in that way I had to view it a bit differently. Some people will complain that it's long and most of it is drawn out just by the narrator talking about things and not actually doing it. Well, if you read it as a confession, if you read it as though this is from an actual person sitting down with a pen and paper and unburdening himself of his crimes and passions, then who are we to say that it's drawn out? It's how someone lived and thought.
The reader knows the truth from the beginning, but it's interesting to see how the narrator finally finds the truth. And it's interesting to read inside his mind while he commit such crimes and talked to certain people, and so on.
I can't say I was completely satisfied with the ending. I admit, I was thinking it would go a different way. Either my way or the way the author wrote it, is still not a happy ending.
I can't say too much without giving things away, but I really don't know what kind of person to recommend this to. I'd say it's worth a try to anyone. You may be surprised.
